Blosnavirus
# Blosnavirus

Blosnavirus is a genus of viruses, in the family Birnaviridae. Blotched snakehead fish serve as natural hosts. There are two species in this genus.

## Taxonomy

The genus contains the following species:

* Blotched snakehead virus
* Lates calcarifer birnavirus

## Structure

Viruses in Blosnavirus are non-enveloped, with icosahedral and Single-shelled geometries, and T=13 symmetry. The diameter is around 70 nm. Genomes are linear and have 2 segments, around 2.7-3.4kb in length. The genome codes for 6 proteins.

| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
| - | - | - | - | - | - |
| Blosnavirus | Icosahedral | T=13 | Non-enveloped | Linear | Segmented |

## Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Blotched snakehead fish serve as the natural host.
